Potassium permanganate to treat skin infections

[uks]

Potassium is a great addition to any survival kit. It can be used for a host thing.

Water purification: 3 or 4 crystals per liter of water. Stir and leave it for 30 minutes. A light pink colour is what you are after

Fungal and wound cleaning: Add a few more crystals than you would for water purification, until you have a darker tint of pink.

Hand sanitizing: This same solution can be used to wash hands.

Signaling: Dissolve some in water to get a bright pink/purple solution for coloring white or clear colored fabric. You can also spread it on snow to make a visible signal.

Fire starter: 1 part sugar , 2 parts potassium permanganate, grind into a thin powder and it will light with a spark from a fire steel.

Its can be dangerous in many ways when misused and it does stain with a red/purple tint that can be hard to remove.
